Comparison of the effect of linseed and basil seed mucilages with gum tragacanth and xanthan gum on textural and rheological properties of Iranian white cheese produced by ultrafiltration technique effect of some gums on properties of ultrafiltrated cheese

Abstract

In this study the rheological and textural properties of Iranian white cheese produced by ultrafiltration technique containing gum tragacanth and xanthan each in the range of 0-0.1%, and basil seed and linseed mucilage each in the range of 0-0.2% were evaluated. According to the results obtained, values of Elastic (G/) and viscous (G//) moduli increased with increasing frequency sweep in all the cheese samples. G/ was always greater than G//. The values of G/ and G// in the sample containing 0.05% of gum tragacanth, 0.05% of xanthan gum and 0.1% of basil seed mucilage and the sample containing 0.05% of xanthan gum, 0.1% basil seed and 0.1% linseed mucilage were maximum. Also, in samples containing 0.1% of xanthan gum and 0.2% of linseed mucilage and containing 0.1% of gum tragacanth were minimum. With increasing basil seeds mucilage in the samples, hardness, cohesiveness, gumminess and chewiness increased in comparison with the control sample (p < 0.01). According to the results obtained, for preparation of white cheese produced by ultrafiltration technique, application of 0.05% of gum tragacanth, 0.05 % of xanthan gum and 0.1 % of linseed mucilage, is recommended.
